Kevin Winter/Getty Images Actor Steve Buscemi with the cast of 'Boardwalk Empire' accept the Outstanding Performance by an Ensemble in a Drama Series award onstage during the 18th Annual Screen Actors Guild Awards at The Shrine Auditorium on January 29, 2012 in Los Angeles, California.

For the second year in a row, HBO's gangster series "Boardwalk Empire" has won Outstanding Performance by an Ensemble in a Drama Series.

Set in Atlantic City, New Jersey during Prohibition, County Treasurer Enoch 'Nucky' Thompson (Steve Buscemi) controls the city's booze, politics and is puppet master from bootlegging operations to the halls of power in Washington, D.C. The series, created by Terence Winter and executive produced by Martin Scorsese and Mark Wahlberg, was inspired by author Nelson Johnson's best-selling non-fiction book of the same name.

Earlier in the evening, Buscemi won the SAG Award for Best Actor in a Drama and joked about the killing of his co-star Michael Pitt at the end of last season. "To all the Michael Pitt fans out there... I know, I'm sorry. Stop yelling at me in the street," he said in his acceptance speech.

HBO has picked up the show for a third season and, presumably, it will be back in the fall.
